Our home energy usage is typically about one fifth of our footprint and a good place to make savings. For the average household, turning the heating down by just 1°C could reduce your footprint by upto 300 kgCO₂ per year (and save you money). Switching to energy saving lightbulbs, improving your insulation and taking a shower rather than a bath will also all reduce your footprint. And don't forget to turn off gadgets and lights that aren't being used!
